   We 
  collected 
  82 
  specimens, 
  12 
  of 
  which 
  were 
  taken 
  alive. 
  

   Many 
  of 
  them 
  are 
  covered 
  with 
  prominent 
  spiral 
  linear 
  ridges, 
  

   which 
  are 
  wanting 
  on 
  others. 
  But 
  the 
  number 
  of 
  specimens 
  

   with 
  intermediate 
  characters 
  is 
  so 
  large 
  as 
  to 
  show

   tinction 
  is 
  not 
  of 
  specific 
  value.
